Tyrannosaurus rex had 'air-con' in its head

[Still Waters]

As a big, active predator, the mighty Tyrannosaurus rex needed a way to cool down.

Now, scientists say that two large holes in its skull acted as a kind of internal "air-conditioning unit", to help the dinosaur lose heat.

These anatomical features on the top of the head were previously thought to have been filled by muscles.

But a team says it's more likely this area was filled with blood vessels that helped T. rex regulate its temperature.

Their tiny arms was strong they could lift over 180 kg. And they didn't roar probably sounded like a turkey  gooble gooble ;-)
